Brian T. Tumolo, 19, of Manorville, N.Y. was charged with third-degree criminal sale of a controlled substance. At 4 a.m. Saturday morning he was arrested for selling heroin to people in the city of Oswego, police said.

According to the police report, Tumolo was reported to have sold the drugs at 1:28 a.m., the same time first responders arrived to treat and transport the two students.

The report did not say whether Tumolo's arrest was related to the overdoses. Oswego police could not be reached for comment Tuesday morning.

Oswego City Police said Monday they will not release the names of the students, including one who died. University Police also declined to release their names, citing an ongoing investigation.

Tumolo is not listed in SUNY Oswego's people search as a student, or other member of the university community.

Oswego police told syracuse.com Monday that first responders do not currently have access to Narcan, a life-saving nasal spray that immediately reverses the effects of heroin.

But Lt. Paul Conzone of the Oswego Fire Department said that ambulances and fire engines carry Narcan in medication bags and administer the antidote to patients any time there is a suspected narcotic overdose and breathing problems.

Conzone said that Narcan was used on the overdose calls in the city of Oswego over the weekend.

The students, two of whom were found on Bridge Street, were likely participants in the Bridge Street Run, Capt. Charles Tonkin of the Oswego police department said, but he said he didn't think the bar crawl, a tradition in Oswego since the '60s, played a key part in the overdoses.

"We believe they probably were participating," Tonkin said. "But was it because of the Bridge Street Run? No."
